Standardized Ginkgo Biloba Leaf Extract
Also known as: Ginkgo, Maidenhair Tree, Ginkgo biloba
Overview
Ginkgo biloba is an ancient tree native to China, renowned for its medicinal properties derived from its leaves. The standardized extract is a rich source of flavonoids and terpenoids, compounds known for their antioxidant and anti-inflammatory effects. Primarily, Ginkgo biloba is used to enhance cognitive function, improve memory, and support cardiovascular health. Research suggests it may improve blood flow, protect against neuronal damage, and reduce oxidative stress. It is available in various forms, including capsules, tablets, and liquid extracts, with standardized extracts ensuring consistent levels of active compounds. While generally considered safe, caution is advised due to potential bleeding risks, and it is essential to consult with a healthcare provider before use, especially when taking other medications.
Benefits
Ginkgo biloba has shown promise in several key areas. A meta-analysis indicated that Ginkgo biloba, when combined with donepezil, significantly improved cognitive function in dementia patients compared to donepezil alone. Furthermore, studies suggest that Ginkgo biloba extract (GBE) can improve respiratory function and reduce fibrosis markers in patients with Idiopathic Pulmonary Fibrosis (IPF). Additional research points to potential benefits for cardiovascular health and antioxidant effects. Elderly individuals experiencing cognitive decline may particularly benefit from Ginkgo biloba supplementation. However, it is important to note that while these benefits are promising, more research is needed to fully understand the extent and consistency of these effects.
How it works
Ginkgo biloba's mechanism of action is multifaceted, primarily involving its antioxidant, anti-inflammatory, and potential antiplatelet effects, which are attributed to its flavonoid and terpenoid components. It interacts with the cardiovascular, nervous, and respiratory systems. Specifically, it may improve blood flow by promoting vasodilation and reducing blood viscosity. The active compounds in Ginkgo biloba also target platelet aggregation pathways and reduce oxidative stress, protecting cells from damage. These actions collectively contribute to its cognitive-enhancing and cardiovascular benefits.
Side effects
Ginkgo biloba is generally considered safe, but it can cause side effects in some individuals. Common side effects, occurring in more than 5% of users, include gastrointestinal upset and headaches. Less common side effects (1-5%) may include dizziness and allergic reactions. Rare but serious side effects (less than 1%) include severe allergic reactions and bleeding complications. Ginkgo biloba can interact with anticoagulants and antiplatelet drugs, increasing the risk of bleeding. It is contraindicated in pregnancy, breastfeeding, and individuals with bleeding disorders. Elderly individuals should be particularly cautious due to potential interactions with other medications. It is crucial to consult with a healthcare provider before starting Ginkgo biloba, especially if you have pre-existing medical conditions or are taking other medications.
Dosage
The typical recommended dosage of standardized Ginkgo biloba extract is between 120 to 240 mg per day. A minimum effective dose is generally considered to be 120 mg per day. It is generally not recommended to exceed 240 mg per day. Consistent daily dosing is recommended for optimal results. Ginkgo biloba is typically available in capsules or tablets containing standardized extract. Bioavailability may be enhanced when taken with food. Monitor for any adverse effects and consult with a healthcare provider for personalized recommendations.
